Enclosure Reassembly and Recharging
REASSEMBLY
When the enclosure is disassembled, it should be recharged after reassembly and prior to installation.
Recharging requires the use of a Pelco EH8000RKIT recharge kit (or equivalent) and applicable O-ring kit,
part EH8004ORKIT or EH8006ORKIT.
To prepare the enclosure for recharging:
1. Once the enclosure has been disassembled, remove the O-ring from the rear plate and install a new
O-ring in the O-ring groove.
2. After installing the new O-ring, smear a liberal amount of O-ring lubricant (supplied) on the exterior
surface of the O-ring and rear plate. Replace the desiccant bag in the enclosure with the new one
(supplied).
3. Slide the camera sled back into the body making sure the front lip of the sled is under the retaining
bracket of the enclosure. When fully installed, the rear plate will fit firmly into the rear opening of
the housing, and the retaining grove will be fully visible.
4. Reinstall the spiral retaining ring in the grove in the rear of the enclosure.
RECHARGING
1. Pressurize the inside of the enclosure using the EH8000RKIT recharge kit. Connect the regulator to
the tank by threading the nut into the socket of the tank valve. Tighten with a wrench. This regulator
is factory preset for 12 psi (83 kPa).
2. Once the regulator has been secured to the tank, open the regulator valve first and then the tank
value.
3. Remove the Schrader valve cap (refer to Figure 1 on page 5). Affix the self-holding tire chuck to the
Schrader valve.
4. To reduce the purge time necessary to remove oxygen from the enclosure, position it so that the
window is pointing up.
5. Remove the plastic cap on the pressure relief valve on the rear of the enclosure. Use a small
screwdriver to hold the valve open. Allow the nitrogen to flow through the enclosure until the
humidity indicator registers the lowest humidity level, changing color from pink to blue. (The
humidity indicator can be viewed through the front window of the enclosure by looking at the inside
top of the enclosure.) Once the humidity indicator registers the lowest level, remove the screwdriver
and allow nitrogen to continue to flow into the enclosure until you no longer hear the flow of
nitrogen from the tank to the enclosure.
6. Remove the tire chuck from the Schrader valve. Replace the Schrader valve and pressure relief valve
caps.
POWER CONNECTION
1. Reconnect the ground wire to the ground stud on the back of the enclosure.
2. Reconnect the electrical connector and turn on power.
